If you want your wooden chopping board to last 5 to 10 years, oil it every 3 to 4 weeks with a food safe mineral oil or board conditioner, using roughly 5 to 10 ml per side on a 45x35cm board. The basic method is simple: clean, dry, apply oil in thin coats, let it soak for at least 6 hours, then wipe off any excess.
How to oil a wooden chopping board step by step
Here is a practical, repeatable routine you can use on any wooden or bamboo kitchen board, whether it is a large 45x35cm butcher style block or a slimmer 38x28cm prep board.
-
Wash and dry the board
Wash the board with warm water and a small amount of mild washing up liquid. Scrub both sides, then rinse. Dry immediately with a clean tea towel and stand it upright so air can reach both faces. Let it dry for at least 2 to 3 hours before you oil. Never soak a wooden cutting board or put it in the dishwasher, as that encourages warping and cracking. -
Check the surface
Run your hand across the board. If it feels rough or raised, lightly sand with fine 240 grit sandpaper, always following the grain. Wipe away dust with a slightly damp cloth, then dry again. This step helps oil soak in evenly and keeps knife edges happier. -
Choose the right oil
Use a food safe mineral oil or a dedicated board conditioner that usually blends mineral oil with natural waxes like beeswax. Avoid olive oil, sunflower oil and other cooking oils, as they can turn sticky and rancid over time. For Deer & Oak bamboo and acacia boards we recommend a clear, odourless mineral oil. -
Measure the oil
For a 45x35cm board such as the Deer & Oak Large Bamboo Board, start with about 5 to 10 ml of oil per side. For a 38x28cm board, 3 to 5 ml per side is usually enough. You want a thin, even film, not puddles. -
Apply in thin coats
Pour a small line of oil down the centre of the board. Use a lint free cloth or paper towel to spread it across the surface in circles, then follow the grain. Cover the entire face, including the edges and any juice grooves. Flip the board and repeat on the other side. If the board looks dry in spots after 5 minutes, add another 1 to 2 ml and work it in. -
Let the board soak
Lay the board flat on a protected surface and leave it for at least 6 hours. Overnight, around 8 to 10 hours, is ideal for thicker boards like the Deer & Oak Large Acacia Board. The wood will absorb what it needs, which helps resist water and stains. -
Wipe off the excess
After soaking, buff the board with a clean dry cloth to remove any oil that has not soaked in. The surface should feel silky and dry to the touch, not greasy. -
Optional wax finish
If you use a separate wax, apply a very thin layer with a cloth, let it sit for 15 to 20 minutes, then buff well. Wax gives an extra barrier against moisture, which is useful if your board regularly meets juicy meats or tomatoes.
How often should you oil a wooden cutting board?
As a simple rule, oil your kitchen board every 3 to 4 weeks if you cook most days. If the board looks dry, pale or feels rough before that, oil it sooner. Heavy use or very dry centrally heated homes may need a top up every 2 weeks.
New boards, even pre oiled ones, benefit from a short "seasoning" plan:
- First month: oil once a week
- Months 2 to 3: oil every 3 weeks
- After 3 months: move to your normal schedule, usually every 3 to 4 weeks
Deer & Oak boards like the Bamboo Double Pack and the Acacia board range arrive pre oiled, so you can start using them immediately. Still, a light coat in the first 2 to 4 weeks helps build a deeper protective layer.
Why oiling your kitchen board actually matters
Oiling is not just about looks. It solves several specific problems that shorten the life of a wooden chopping board:
-
Cracking and warping
Dry wood shrinks. Regular oiling slows moisture loss, which helps keep a 45x35cm board flat on the worktop rather than cupping at the edges. -
Staining and smells
An oiled surface absorbs less beetroot juice, curry or onion. That means fewer deep stains and less lingering odour. On boards used for raw meat, oiling plus proper washing reduces the chance of juices soaking deep into the grain. -
Rough, knife dulling grain
Dry fibres stand up and feel fuzzy. Oiling lays them down again, so your knife glides instead of catching. Over a year, that can help keep your knives sharper for longer. -
Shortened lifespan
A neglected board might last 1 to 2 years before it splits. With regular oiling every 3 to 4 weeks, a quality acacia or bamboo board can often stay in service for 5 to 10 years.
Choosing the right board to oil: bamboo vs acacia
Different woods respond slightly differently to oil, which is why product choice matters. Here is how some of the Deer & Oak range behaves in normal kitchen use.
- Moso bamboo boards such as the Large Bamboo Board and the Medium Bamboo Board are naturally dense and absorb a moderate amount of oil. They suit everyday chopping of vegetables, fruit and bread, and need oiling roughly every 3 to 4 weeks.
- Carbonised bamboo boards like the Carbonised Bamboo Board have a richer colour and slightly more open grain from the heat treatment. They usually benefit from slightly more oil per session and are a good match for serving as well as chopping.
- Acacia wood boards such as the Large Acacia Board and Medium Acacia Board are a little heavier and feel very solid under the knife. They often need oiling every 2 to 3 weeks if you use them for meat or citrus, as those foods draw out moisture faster.
If you want a ready made set that is simple to maintain, the Deer & Oak chopping board sets give you a mix of sizes that all follow the same oiling routine.

Who this is for and who it is not for
Ideal for:
- Home cooks who use a wooden chopping board at least 3 to 4 times a week and want it to last 5 to 10 years
- People who own bamboo or acacia cutting boards and want a clear, low effort care routine
- Anyone who has invested in a heavier board such as a 45x35cm butcher style block and wants to avoid warping or cracking
- Hosts who use their boards for serving cheese or charcuterie and want them to stay presentable for guests
Not recommended for:
- People who prefer dishwasher safe plastic boards and do not want to hand wash or oil anything
- Commercial kitchens that need boards sanitised in industrial dishwashers several times a day
- Anyone unwilling to spend 10 to 15 minutes once a month on basic board maintenance
- Situations where cutting boards are constantly soaked or left outdoors in the rain
Frequently asked questions
Q: What is the best oil to use on a wooden chopping board?
A: The best oil for a wooden chopping board is a food safe mineral oil or a dedicated board conditioner that contains mineral oil and natural waxes. These stay stable, do not go rancid and soak evenly into bamboo and acacia. Avoid cooking oils like olive, rapeseed or sunflower, as they can become sticky and smell unpleasant over time.
Q: How do I know when my cutting board needs oiling?
A: If water no longer beads on the surface, the colour looks patchy or pale, or the board feels rough to the touch, it is time to oil it. You may also notice that stains from beetroot or berries soak in faster when the board is dry. As a guide, most home cooks find every 3 to 4 weeks is about right.
Q: Can I use the same routine on bamboo and acacia kitchen boards?
A: Yes, the cleaning and oiling steps are the same for both bamboo and acacia boards. The only difference is that acacia, especially in thicker 45x35cm sizes, may need slightly more frequent oiling, around every 2 to 3 weeks if you use it heavily. Always treat both sides of the board to keep it stable.
Q: Is it safe to cut raw meat on an oiled wooden board?
A: It is safe as long as you wash the board promptly with hot water and mild washing up liquid, dry it well and oil it regularly. Many cooks keep one board, such as a Deer & Oak Large Bamboo or Acacia board, mainly for meat and another for bread and fruit. Regular oiling helps stop juices soaking deep into the grain, which supports hygiene.
